Unusual Quasiparticle Alignments in $^{168, 169}$W

ORAL

Abstract

While the basic concepts of normal deformed low-spin quasiparticle excitations are thought to be well understood, unusual behavior may still be encountered. A recent data set obtained using the Gammasphere spectrometer on $^{168}$W and $^{169}$W is a case in point. Anomalies were observed between the expected [1] and observed alignment gains and crossing frequencies in the positive parity bands for both nuclei. Analysis of these structures will be discussed along with comparisons to neighboring nuclei [2, 3].\\[4pt] [1] D. R. Jensen \textit{et al.}, Phys. J. A \textbf{8}, 165 (2000);\\[0pt] [2] R. B.
